Synopsis
========

Multiple vulnerabilities have been found in Apache Tomcat, the worst of
which could lead to privilege escalation.

Background
==========

Apache Tomcat is a Servlet-3.0/JSP-2.2 Container.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  www-servers/tomcat           < 8.0.36                  >= 7.0.70
                                                            >= 8.0.36

Description
===========

Multiple vulnerabilities have been discovered in Tomcat. Please review
the CVE identifiers referenced below for details.

Impact
======

A remote attacker may be able to cause a Denial of Service condition,
obtain sensitive information, bypass protection mechanisms and
authentication restrictions.

A local attacker, who is a tomcat's system user or belongs to tomcat=E2=80=
=99s
group, could potentially escalate privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache Tomcat users have to manually check their Tomcat runscripts
to make sure that they don't use an old, vulnerable runscript. In
addition:

All Apache Tomcat 7 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-servers/tomcat-7.0.70:7"

All Apache Tomcat 8 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-servers/tomcat-8.0.36:8"
